WASHAIBLE DYED SILK PIECE GOODS AND PROCESS OF DYEING THEM.

No Drawing.

To all whom it may concern:

Be it known that I, JosnrH Saran, a citizen of the United States, a resident of Hawthorne, in the county of Passaic and State of New Jersey, have invented a certain new and useful \Vashable Dyed Silk Piece Goods andlroccsses of Dyeing Them. of which the following is a specification.

This invention relates to a new article of manufacture, or product consisting of a washable silk fabric which has been dyed in the form of piece goods, and the processes of producing and dyeing such fabrics.

Hitherto no successful way has been found of dyeing silk piece goods'in various colors so as to produce a washable article. that is one that may be washed in warm soap water without becoming spotted or irregularly changed in its shadeof color. My invention has succeeded in producing silks dyed in various colors in the form of piece goods. and it has furthermore achieved the production of washable silks which will not impart their colors to a washin liquid such as an aqueous soap solution.

y invention has accordingly as an object the production of washable silks dyed in any desired shade of color in the form of piece goods. and it has as a further object the production of washable silks which will not impart color to the washing liquid. It is also an object of my invention to produce washable silks dyed with colors of many kinds and shades that are relatively inexpensive, and to fix these colors on the silks.

A further object is to avoid the uneven dyeing and undesirable results obtained by mordanting silk previous to the beginning of the dyeing operation. A. still further object is to produce piece goods of silk which will be relatively fast to perspiration, light, and ironing. It is also an object to produce the above results with pure silk and also with mixed goods.

Further objects will appear hereinafter.

In the preferred embodiment of my invention I proceed by four different processes according to whatever color and shade is dei tion filed December 1, 1922. Serial No. 604,890. i

sired, eachprocess varying more or less from the other in certain details. I shall thereso fore describe each process in detail. For the purpose of illustration of the application of each process to the production of certain colors. I will list the colors named on the Color Card of America issued by The Textile Color (ard Association of the U. S. (5th ed).

When the goods match the objective sample, there are added to the dye bath of 250 gallons-liquor. 5 lbs. tannic acid (C H (),,.:2H,()) and the goods are worked for one hour continuously at aboil. They are then well washed and treated in a cold bath of water comprising two hundred and fifty gallons. with 4% lbs. tartar emetic (CQLO KSbog H O) for 40 minutes. After this they are well washed and then cleaned in a soap bath at 160 F. The treatment is now concluded by washing Well and acidulating.

Process #3.

This process is applicable for the following colors:

They are then treated with about six pounds oftannic acid in a water liquor comprising about two hundred and fifty gallons of liquor, at a temperature of 160 F. for one hour. They are then washed. well and treated in a cold water bath of two hundred and fifty gallons with 41.5 lbs. tartar emetic for 40 minutes, after which they are again well washed.

They are then washed well and developed with 6 lbs. beta napthol in 250 gallons cold water, worked well 01040 minutes,and then washed. At this point the treatment is continued according to process #1, beginning at the first.

step thereof, for the purpose of dyeing to.

the shade desired with basic or direct dyes. The goods as finally dyed are given a cleans ing bath of soap water at a boiling temperature and worked for 40 minutes, then washed. and acidulated, substantially as in the final slcp of said process #1.

In the four above-described processes various classes of dyes are mentioned for use in the respective processes, and it is desired to state here some examples of the dyes falling under each class. As basic dyes may be used brilliant green, Victoria blue, rhodamine (red). thiotlavine T (yellow), and methyl violet 0 B (blue) and. R (red); as direct dyes, pontamine green BBX, diazolinc dark substantially all of theothcr vat dyes; as

sulfur dyes. sulfur yellow, sulfur blue, sulfur brown, and substantially all of the other sulfur dyes. This list is illustrative, not exhaustive, as other dyes may be used according to their nature and shade.

For producing a black I proceed as folin a bath composed of 500 gallons of water, 30% by weight of fustic extract, 10% by weight of hematine extract oxidized logwood. The

goods are worked in the liquor at the boiling" temperature for :20 minutes, and then to the same liquor are added 25% by weight of black iron, 4% by weight of blue stone, and 20% by Weight acetic acid (to dissolve precipitate in the bath). The goods are Worked at the boiling temperature for one hour, and are then washed well. The goods are now treated in another bath composed of 500 gallons boiling water, 30% hematine extract, and 50 lbs. soap, and they are worked therein for one hour, and then washed. The next step consists in treating the goods in a bath of 500 gallons water at 160 F, containing tannic acid in the proportion of six pounds tannic acid per 250 gallons of dye liquor. This is followed by the tartar emetic treatment as in process #3, namely, four and-one-half pounds of tartar emetic per two hundred and fifty gallons of dye liquor. The final dyed goods are given two cleansing soap baths at a boiling temperature, and then washed well and acidulated. There is thus produced a washable black which will not impart a black or dark color to a wash ing soap liquid below 160 F. or thereabouts.

As a result of the above processes there are produced varieties of dyed silk piece goods which are washable, that is, they may be -washed in water containing soap at a temperature of 110 F., and they will, in. most cases, stand 180 F., withoutsuffering unevenness in shade or color. or distinct loss of color. In addition to the highly desirable quality of being washable, these piecesilks have also the property of being washable wit out imparting any substantial amount. of their color to the washing liquid, such as water or soap solution. These results have not hitherto been achieved with silk piece goods dyed in all shades of colors. The alizarin dyes, which are used for the production of fast colors, are expensive and exist only in a limited number of shades. My new silk goods may accordingly be distinguished from other silk goods by noting several'of their qualities as follows: They have been dyed in the piece, and are fast to washing in lukewarm soapy water about 110F.) but not fast to boiling soapy water although, as before stated, they may often stand higher temperatures than 110 F.. up to about 160 F. Another feature of my new goods is that they may be produced and sold in all colors and shades of color, thus distinguishing, for

example. from alizarin dyed goods. A still further characteristic of my silk piece goods is that they will not bleed in cold water. that is, impart color thereto, nor will they readily show the marks and effects of perspiration. They may be washed together with silk, cotton, artificial silk, wool, etc, without staining them. the temperature being about 110 F. as above. They also have excellent fastness to light and ironing.

While my silk piece goods have been described as being of unmixed silk, it is also possible to make mixed silk goods, such as silk and cotton, by the above-described processes according to the nature of the result desired.

In methods 1 to 4 inclusive I have de--' scribed processes of dyeing silk in. various colors, and in method 5 I have described the process of dyeing black, so that by the use of the words colored silk, or their equivalent, 1 mean colors other than black.
